elytron, yet vary very much both in the width and form of the second band. Others 

 from Costa Rica have this band very narrow and sometimes undulate, and these 

 represent a distinct variety. 



We figure two examples, one from Bugaba (fig. 15) and one from Cache (fig. 16). 



SCAPHIDOMORPHUS.

 Scaphidomorphus (div. 1), Lacordaire, Monogr. Erotyl. p. 481. 



Chapuis, adopting Erichson's name Prepopharus for the second and third divisions, 

 restricts this genus to two large species which have their prosternum with a keel and 

 the labium emarginate. 



Crotch seems to have regarded these two species as forms of one variable insect ; 

 Gemminger and Harold, on the other hand, retain them as distinct. I have not seen 

 specimens of S. h-punctatus from Central America.

This is a large and showy species, varying very considerably in size (one example 

 from Chiriqui measuring only 13 millim., while others reach 20 millim. in length), and 

 also in the dimensions of the red spots. The second spot is more or less divided, and in 

 several specimens from Bogota (in Crotch's collection) forms only two small spots ; in a 

 singular variety in my own collection the internal one only of the two spots remains. 

 The colour of the spots also varies from blood-red to pale yellow. 



PREPOPHARUS.

 Scaphidomorphus, Lacordaire, Monogr. Erotyl. p. 484 (pars) . 



This genus includes the second and third divisions of Scaphidomorphus of Lacordaire. 

 Eighteen species have been described. Prepopharus is peculiar to Tropical America, 

 Mexico being the northern limit of the genus. . The species have frequently an opaline 

 reflection. The genus is evidently rather closely allied to Zonarius.
